Considering the significance of ancestry through the prism of mixed-race identity.

People of mixed ancestry promise to be a significant percentage of the population of the United States in the 21st century. This article describes a qualitative study of 20 older mixed-race adults of African-American-white and Asian-American-white ancestries and focuses on how the participants construct identity. Using grounded theory methodology, racial identity did not emerge as a singular, distinct entity in this study, and five dimensions of racial identity were observed. Significant differences in patterns of identity dimensions were noted for the two mixed groups. Implications for nursing practice are discussed.
